FIG. 1 is a schematic diagram illustrating an application scenario of an environmental parameter measurement system 110 according to some embodiments of the present disclosure. In some embodiments, the environmental parameter measurement system 110 may be installed inside a house building 100. The house building 100 may be a residential building, a public building, and/or an industrial building, or the like. In some embodiments, the parts or components of the environmental parameter measurement system 110 may be mounted on different locations, rooms, buildings, or other places. A sensing device, a data obtaining device, a data processing device, a data storage and other devices in the environmental parameter measurement system 110 may communicate with each other via a wireless connection or a wired connection.

In some embodiments, the environmental parameter measurement system 110 may measure one or more environmental parameters and compensate the measured value of the environmental parameters. In some embodiments, the environmental parameter may be temperature, relative humidity, absolute humidity, a gas pressure, a partial pressure of a certain gas (e.g., nitrogen, oxygen, or carbon dioxide, etc.), particulate matter in the air, etc. As an example, the measured value of the environmental parameter may be a current measured value of the environmental parameter.

It may also exit a second sensing device 120 and a heat generating device 130 inside the building 100. The heat generating device 130 may be a device generating heat and dissipating the heat outward during operation. In some embodiments, the heat may be generated based on a thermal effect of a current caused by the operation of the heat generating device 130. In some embodiments, the heat generating device 130 may be a powered device, such as a household electric appliance. As an example, the household electric appliance may be an air conditioner, a television, a temperature and humidity measuring device, a control panel, etc. In some embodiments, the environmental parameter measuring system 110 may be integrated with the air conditioner, the television, the temperature and humidity measuring device, or the control panel. In some embodiments, when the environmental parameter measurement system 110 is integrated with the control panel, the components of the environmental parameter measurement system 110 for sensing, collecting data, and displaying data may be integrated into the control panel. For example, the temperature of the environment surrounding the control panel may be measured by a built-in temperature sensor in the control panel. The control panel may upload the measured temperature data to a network server for processing. The control panel may also download the processed data from the network server and display the downloaded data via an LCD screen or an LED screen.

The second sensing device 120 may collect reference data of one or more environmental parameters, such as a temperature reference data, a humidity reference data, etc. The reference data may include one or more measured values of the environmental parameter under different measurement conditions. The measurement conditions may have an effect on the measured value of the environmental parameter. The measurement conditions may include the material about a building wall, the electric power of the heat generating device 130, the power-on duration of the heat generating device 130, the measured value of the current ambient temperature, and the measured value of the current indoor humidity, etc.

Wherein, the value of D1 may range from 0 meters to 3 meters, or 0 meters to 5 meters, or at least 1.5 meters. In some embodiments, the influence of the heat generating device 130 on the reference data measured by the second sensing device 120 may be negligible. In some embodiments, when comparing the standard data measured by the second sensing device 120 along with the heat generating device 130 with the standard data measured by the second sensing device 120 without the heat generating device 130, and the difference between them in the range of 1%, 2%, 3%, 5%, 8%, or 10%, or the like, it may be considered that the effect of the heat generating device 130 on the reference data measured by the second sensing device 120 may be negligible. In some embodiments, the second sensing device 120 may be used for correction of the environmental parameter measurement system 110 before leaving a factory. In some embodiments, the environmental parameter measurement system 110 may not include the second measurement device 120.

As an example, the reference data may include a measured value of the same current ambient temperature, an electric power of the same heat generating device, and a position relative to the system 110 or a portion thereof (e.g., the first sensing device 201 of FIG. 2, etc.), reference data of the environmental parameter measured by the second sensing device 120 (e.g., temperature reference data and humidity reference data, etc.) under difference power-on duration conditions of the heat generating device. In some embodiments, the deviation of the environmental parameter measured value may be determined according to the reference data of the environmental parameter. In some embodiments, a reference environmental parameter time table may be generated, for example, a reference temperature time table, a reference humidity time table, etc., according to the reference data of the environmental parameter or the deviation of the environmental parameter measured value. In some embodiments, the reference temperature time table may represent a relationship between a reference temperature and a power-on duration.

The determination unit 430 may be connected with the data interface unit 410, the data processing unit 420, and/or the storage unit 440. In some embodiments, the determination unit 430 may select an algorithm for the data processing unit 420 to perform a data processing. As an example, the determining unit 430 may select an algorithm for a compensating temperature time relationship generated by the quasi-reference temperature time relationship.

It should be noted that the above description of the data processing module 222 is merely provided for convenience of description and not intended to limit the present disclosure to the scope of the embodiments. For persons having ordinary skills in the art, modules may be combined in various ways, or connected with other modules as sub-systems. Various variations and modifications may be made under the teaching of the present disclosure. However, those variations and modifications may not depart from the spirit and scope of this disclosure.

FIG. 5 is an exemplary flowchart illustrating a process of compensating the environmental parameter according to some embodiments of the present disclosure. In some embodiments, the compensation process of the environmental parameter may be implemented by the data processing module 222.

In step 502, the current measured data may be obtained. The measured data may include the current measured data of the environmental parameter, such as a current measured value of temperature, a current measured value of humidity, etc. The current measured data may include a measurement condition of a current environmental parameter, for example, the current electric power value of the heat generating device 130, the current power-on duration of the heat generating device 130, the measured value of the current ambient temperature, or the like, or any combination thereof. In some embodiments, the current measured data may be obtained by the first sensing device 201.

In step 504, the quasi-reference data may be selected from the reference data based on the current measured data. In some embodiments, the reference data may include reference measured data of an environmental parameter under different measurement conditions, for example, powers of different heat generating devices, power-on durations of different heat generating devices, or under the conditions of the measured value of different reference ambient temperatures, the reference measured data of the environment parameter. The reference measured data of the environmental parameter may be obtained according to the process shown in FIG. 8 and its description. In some embodiments, the measurement condition that is closer to the current measured data may be determined according to the current measured data, and the reference data under the condition may be selected as the quasi-reference data. The “closer” as used herein may indicate the ratio of one or more measurement conditions (e.g., ambient temperature, humidity or an electric power value) of the temperature time relationship to the current corresponding measurement condition may be within a range, for example, 95% to 105%, 90% to 110%, or 85% to 115%, etc.

In step 506, the compensated data may be generated based on the quasi-reference data and the current measured data. In some embodiments, the compensated data of the current measured data may be generated according to the quasi-reference data.

It should be noted that the above description of the environmental parameter compensating process is merely provided for convenience of description and not intended to limit the present disclosure to the scope of the embodiments. It will be understood that for persons having ordinary skills in the art, modules may be combined in various ways, or connected with other modules as sub-systems. Various variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications may not depart from the spirit and the scope of the present disclosure. For example, other operations or determinations may be added between the step 502 of obtaining the measurement data and the step 508 of outputting the compensated data. For example, the obtained current measured data may be stored and backed up. Similarly, a storage backup step may be added between any two steps in the process of the FIG. 5.

FIG. 6 is a schematic diagram illustrating the data processing unit 420 according to some embodiments of the present disclosure. The data processing unit 420 may include a preprocessing sub-unit 610, a generating sub-unit 620, and a compensating sub-unit 630.

The preprocessing sub-unit 610 may perform preprocessing operations on the received data. In some embodiments, the preprocessing sub-unit 610 may perform on filtering, processing dark current, removing noise, and geometric correction, or the like, or any combination thereof. In some embodiments, the preprocessing sub-unit 610 may filter the received data to select the required data. In some embodiments, the preprocessing sub-unit 610 may be connected with the generating sub-unit 620. As an example, the preprocessing sub-unit 610 may transfer the pre-processed data to the generating sub-unit 620.

The generating sub-unit 620 may determine the reference temperature time relationship. In some embodiments, the generating sub-unit 620 may determine the relationship between the reference temperature and the running time of the heat generating device 130 (referred to as “the reference temperature time relationship”) according to the reference data. In some embodiments, the reference data may be obtained by the second sensing device 120. As an example, the generating sub-unit 620 may determine the relationship between the reference temperature and the time under different measurement conditions, with the reference data under different measurement conditions. In some embodiments, the measurement condition may be a combination of the power of the heat generating device 130 and the measured value of the reference ambient temperature. As an example, the measured value of the reference ambient temperature may have four temperature values including T_(A), T_(B), T_(C), and T_(D), and the power of the device may have three electric power values including P₁, P₂, and P₃. The different measurement conditions may be twelve kinds of combinations of the aforementioned four temperature values and the aforementioned three electric power values. The reference temperature data of the heat generating device 130 under different power-on duration conditions may be respectively measured based on the 12 combinations, and the 12 reference temperature time relationship tables may be generated. As an example, the selection of T_(A), T_(B), T_(C), and T_(D) may be arbitrary, or determined based on the possible upper temperature limits and the possible lower temperature limits of the actual use environment of heat generating device 130. For example, the T_(A) and the T_(D) may be selected as the upper temperature limit and the lower temperature limit, respectively. The T_(B) and the T_(C) may be determined as follows: in a state of P₁, under the condition of the T_(D), a required time from a stable temperature deviation in the non-operating state of the heat generating device 130 to the stable temperature deviation in the running state of the heat generating device 130 for the first time, may be determined as t_(a); in the state of the P₁, under the condition of the T_(A), the required time from a stable temperature deviation in the non-operating state of the heat generating device 130 to the stable temperature deviation in the running state of the heat generating device 130 for the first time, may be determined as t_(b); then T_(B) and T_(C) may select any node between t_(a) and t_(b), for example, the temperatures of (t_(b)−t_(a))/3 and 2(t_(b)−t_(a))/3. Similarly, P₂ may be determined as follows: P₁ and P₃ may be selected as the upper limits of the power of the heat generating device and lower limits of the power of the heat generating device. In the state of the P₁, under the condition of the T_(A), the required time from a stable temperature deviation in the non-operating state of the heat generating device 130 to the stable temperature deviation in the running state of the heat generating device 130 for the first time, may be determined as t_(c); in the state of P₁, under the condition of the T_(A), the required time from a stable temperature deviation in the non-operating state of the heat generating device 130 to the stable temperature deviation in the running state of the heat generating device 130 for the first time, may be determined as t_(d); then any node between t_(a) and t_(b), for example, the temperature of (t_(c)−t_(d))/2, may be selected. In some embodiments, the temperature deviation may be a deviation of the measured value of the current ambient temperature relative to the measured value of the ambient temperature reference ambient temperature. The stable temperature deviation may refer to a temperature deviation reached after the heat generating device 130 remains in the running state or the non-operating state for a long time. The longer time herein may be 1 hour, 2 hours, 5 hours or other time.

The compensating sub-unit 630 may generate the compensated data of the measured value of the current temperature. In some embodiments, the measured value of the current temperature may be obtained by the first sensing device 201. In some embodiments, the compensating sub-unit 630 may select a quasi-reference temperature time relationship of one or more measured value of the current temperature and generate a compensating temperature time relationship. In some embodiments, N reference temperature time relationships closer to the current measurement condition may be selected as the quasi-reference temperature time table, wherein N may refer to any positive integer. Herein, the “closer” may refer to a ratio of one or more measurement conditions in the temperature time table (e.g., the measured value of the ambient temperature, a measured value of the ambient humidity, or the electric power value) to the values of current corresponding measurement conditions may not exceed a range, for example, 95% to 105%, 90% to 110%, or 85% to 115%. In some embodiments, the compensating sub-unit 630 may generate the compensating temperature time table according to the quasi-reference temperature time table. As an example, the compensating sub-unit 630 may perform a fitting calculation against the quasi-reference temperature time table to generate a compensating temperature table. In some embodiments, the compensating sub-unit 630 may also compensate for the current measured value of the temperature according to the compensating temperature time table. The fitting calculation method herein may be a combination of one or more of the aforementioned interpolation methods or the aforementioned extrapolation methods.

It should be noted that the above description of the data processing unit 420 is merely provided for convenience of description and not intended to limit the present disclosure to the scope of the embodiments. For persons having ordinary skills in the art, modules may be combined in various ways, or connected with other modules as sub-systems, and various modifications and transformations in form and detail may be conducted under the teaching of the present disclosure. However, those modifications and transformations may not depart from the spirit and scope of the present disclosure. For example, the preprocessing sub-unit 610 and the generating sub-unit 620 may be combined without the preprocessing sub-unit 610 being reserved. For another example, the generating sub-unit 620 and the compensating sub-unit 630 may be combined, and the compensating sub-unit 630 may implement the aforementioned function of the generating sub-unit 620. In some embodiments, the environmental parameter measurement system 110 may not have the generating sub-unit 620. The reference temperature time relationship used by the environmental parameter measurement system 110 for compensating the measured value of the current environmental parameter may be obtained from the storage device internal to the system 110 (the data obtaining module 221, the user control module 223, the storage module 225, etc.) or the external storage device (e.g., a database on a network, the smartphone, the tablet computer, the laptop computer, a wearable device, or other device, etc.). In some embodiments, the obtained reference temperature time relationship may be measured and obtained by a system having a similar arrangement of the heat generating device 130 and the first measuring device 201 in the environmental parameter measuring system 110. See FIG. 8 and its description.

FIG. 7 is a schematic diagram illustrating a compensating sub-unit 630 according to some embodiments of the present disclosure. The compensating sub-unit 630 may include a lookup sub-unit 710 and a computing sub-unit 720. The lookup sub-unit 710 may look up and select the quasi-reference temperature time relationship in the reference temperature time relationship. In some embodiments, the lookup sub-unit 710 may select one or more reference temperature time relationships close to the current measurement conditions (e.g., the measured value of the current ambient temperature and the electric power value of the heat generating device 130, etc.) as the quasi-reference temperature time table. Herein, the “close” may refer to the ratio of one or more measurement conditions (e.g., the measured value of ambient temperature, the measured value of ambient humidity, or the power value of the heat generating device 130) of the reference temperature time relationship to the value of the current corresponding measurement condition may not exceed a range, for example, 95% to 105%, 90% to 110%, or 85% to 115%.

The computing sub-unit 720 may perform a calculation according to the found quasi-reference temperature time relationship, and generate the compensated temperature time relationship. In some embodiments, the computing sub-unit 720 may perform a fitting calculation (e.g., a combination of one or more of interpolation, extrapolation, etc.) on the found quasi-reference temperature time relationship to generate the compensating temperature time relationship. In some embodiments, the computing sub-unit 720 may calculate according to the compensating temperature time relationship, generate the compensated value of the current measured value of the temperature, and perform compensation on the current measured value of the temperature. As an example, the computing sub-unit 720 may perform linear interpolation or extrapolation based on the compensating temperature time relationship to generate a compensated value. The computing sub-unit 720 may also calculate the compensated value according to other algorithms, for example, other interpolation methods or extrapolation methods. More details on the interpolation methods and the extrapolation methods, please refer to the above, and will not be repeated herein.

It should be noted that the above description of the compensating sub-unit 630 is merely provided for convenience of description and not intended to limit the present disclosure to the scope of the embodiments. For persons having ordinary skills in the art, upon understanding the principle of the system, modules may be combined in various ways, or connected with other modules as sub-systems.

Various variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications may not depart from the spirit and the scope of the present disclosure. For example, in some embodiments, for example, when the compensating temperature time table contains the same or substantially the same temperature data as the current measured value of the temperature, the computing sub-unit 720 may also directly obtain the compensated value of the current measured value of the temperature by the compensating temperature time relationship without the linearity. Interpolation or the extrapolation process. The “substantially the same” may refer to the error between the environmental parameter and the measured value of the environmental parameter after the compensation is within the range of system 110 or the range allowed by the user.

FIG. 8 is an exemplary flowchart for generating a reference temperature time relationship according to some embodiments of the present disclosure. In step 802, a first set of conditions for the heat generating device 130 may be obtained. The first set of conditions may be a combination of one or more measurement conditions. The measurement conditions may include the electric power of the heat generating device 130, the measured value of the ambient temperature, and other parameters that may affect the measurement of the environmental parameter, for example, a wallpaper material of the environment in which the system 110 is located, or the like, or any combination thereof. As an example, the first set of conditions may be a combination of the electric power of the heat generating device 130 and the measured value of the ambient temperature. For example, the first set of conditions may be that electric power of the heat generating device is 90 watts and the measured value of the ambient temperature is 30° C.

In step 804, a first reference temperature may be obtained in a first power-on duration of the heat generating device 130 under the first set of conditions. In some embodiments, the first reference temperature may be measured by the second sensing device 120. The first power-on duration may be any time period t₁ of the device powered on. For example, t₁ may be selected as 5 seconds, 10 minutes, 1 hour, etc. As an example, under the first set of conditions, such as the electric power of the heat generating device as 90 watts and the measured value of the ambient temperature as 30° C., in the first power-on duration of the heat generating device, for example, t₁ as 1 hour, the first reference temperature S1 at this time may be obtained by the second sensing device 120. In some embodiments, the measured value of the first ambient temperature may be obtained by the first sensing device 201 at the same time when the first reference temperature is obtained, that is, in the first power-on duration. The measured value of the first ambient temperature may be a measured value of the ambient temperature obtained by the first sensing device 201 while the first reference temperature obtained. The first measurement deviation of the ambient temperature may be obtained according to the measured value of the first ambient temperature and the first reference temperature as S1.

In step 806, a second reference temperature may be obtained in the second power-on duration of the heat generating device 130 under the first set of conditions. In some embodiments, the second reference temperature may be measured by the second sensing device 120. The second power-on duration may be any time period t₂ (t₂>t₁) when the device is powered on. For example, t2 may be selected as 6 seconds, 16 minutes, 2 hours, etc. As an example, under the conditions of the first set, such as the electric power of the heat generating device as 90 watts and the measured value of the ambient temperature as 30° C., in the second power-on duration of the heat generating device, for example, when t2 is 2 hours, the second reference temperature S2 at this time may be obtained by the second sensing device 120. In some embodiments, the measured value of the second ambient temperature may be obtained by the first sensing device 201 while the second reference temperature is obtained, that is, in the second power-on duration. The measured value of the second ambient temperature may be a measured value of the ambient temperature obtained by the first sensing device 201 while the second reference temperature is obtained. A second measurement deviation of the ambient temperature may be obtained according to the measured value of the second ambient temperature and the second reference temperature data S2.

In step 808, the reference temperature time relationship under the first set of conditions may be generated based on the first set of conditions, the first reference temperature data, and the second reference temperature data. As an example, the first reference temperature (or the first measurement deviation), the second reference temperature (or the second measurement deviation), the first power-on duration and the second power-on duration, may generate a temperature time relationship representing the temperature time relationship under the first set of conditions. As an example, under the first set of conditions, for example, the electric power of the heat generating device as 90 watts, and the measured value of the ambient temperature as 30° C., the reference temperature time relationship may be generated according to the first reference S1, the second reference S2, the first power-on duration 1 hour, and the second power-on duration 2 hours.

The reference temperature time relationship for the system 110 may be generated prior to installation of the system 110. For example, a manufacturer of the system 110 or a portion thereof may generate one or more reference temperature time relationships for the arrangement of the heat generating device 130 and the first measurement device 201. In some embodiments, the one or more reference temperature time relationship may be generated by the second environmental parameter measurement system. The second environmental parameter measurement system has the heat generating device and the measuring device. In some embodiments, the effect of the heat generating device of the second environmental parameter measurement system on its measuring device may be similar to the effect of the heat generating device 130 on the first measuring device 201. As an example, the arrangement of the heat generating device and the measuring device of the second environmental parameter measurement system, for example, a distance or the like, may be the same as or similar to the arrangement of the heat generating device 130 of the environmental parameter measurement system 110 and the first measuring device 201. As another example, the user may debug and generate a reference temperature time relationship suitable for the system 110. As an example, the user may collect data during the commissioning of the first measurement device (e.g., one week, one month, etc.), in conjunction with data collected by the second sensing device during this time, to generate the aforementioned reference temperature time relationship. For another example, the system 110 is officially used for a period of time, for example, one month, one quarter, one year, etc., the user may re-commission the system 110 and update the existing reference temperature time relationship table. In some embodiments, the existing reference temperature time relationship table may be generated during the debugging process before the official use, or loaded into the system 110 by the manufacturer before leaving the factory.

It should be noted that the above description of the process of generating the temperature time relationship is merely provided for convenience of description and not intended to limit the present disclosure to the scope of the embodiments. For persons having ordinary skills in the art, upon understanding the principle of the system, modules may be combined in various ways, or connected with other modules as sub-systems. Various variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications may not depart from the spirit and the scope of the present disclosure. For example, the flowchart is only used as an embodiment of a temperature environmental parameter compensation, and the temperature may be replaced with other environmental parameters, such as humidity, air pressure, partial pressure, airborne particulate matter contents, etc., to achieve a corresponding environmental parameter compensating effect. For another example, under the second group condition, the third group condition . . . , the Nth group condition, the step 802 to the step 808 may be respectively implemented to obtain the temperature time table under different conditions.

FIG. 9 is an exemplary flowchart for compensating the measured value of the current environmental parameter according to some embodiments of the present disclosure. In step 902, the relationship among the measured derivation of the environmental parameter of system 110, the electric power value of the heat generating device of the system 110 and the power-on duration of the heat generating device of the system 110 may be obtained. The measured deviation of the environmental parameter may be the deviation of the measured value of the environmental parameter and the corresponding reference data.

In step 904, the current electric power value of the heat generating device, the power-on duration of the heat generating device, and the measured value of the current environmental parameter may be obtained. In some embodiments, the measured value of the current environmental parameter may be measured and obtained by the first sensing device 201. The first sensing device 201 may be deployed near the heat generating device 130. In some embodiments, when the measured value of the environmental parameter is obtained, the electric power and the power-on duration of the heat generating device 130 may be the current electric power value and the current power-on duration, respectively.

In step 906, a measured deviation of the current environmental parameter may be determined according to the current electric power value, the current power-on duration, the current measured value of the environmental parameter and the relationship. In some embodiments, the existing reference data may be selected according to the current electric power value of the heat generating device and the measured value of the current environmental parameter. In some embodiments, the reference data measured under a set or sets of measurement conditions that are closer to the current electric power value and the measured value of the current environmental parameter may be selected. The “closer” may refer to the ratio of one or more measurement conditions (for example, the measured value of the ambient temperature, the measured value of the ambient humidity, or the electric power value of the heat generating device) of the reference temperature time relationship to the value of the current corresponding measurement condition may not exceed a range, for example, 95% to 105%, 90% to 110%, or 85% to 115%, etc. The measurement condition may be a combination of the electric power value of the reference heat generating device and the measured value of a reference ambient temperature. In some embodiments, the reference temperature parameter time relationship of the selected different electric power of the reference heat generating device and the reference environmental parameter time relationship under the reference ambient temperature conditions may be the quasi-reference temperature time relationship. In some embodiments, a compensating temperature time relationship may be determined according to the selected quasi-reference environmental parameter time relationship. In some embodiments, according to the compensating environmental parameter time relationship, the measured value of the current environmental parameter and the power-on duration of the heat generating device 130, the measurement deviation of the current environmental parameter, that is, the current deviation, may be determined. As an example, the linear interpolation or the extrapolation may be performed based on the compensating temperature time relationship to generate the current deviation. The compensated value may also be calculated according to other interpolation methods, such as a Newton method, a linear interpolation method, a polynomial interpolation method, or extrapolation methods, for example, a linear extrapolation, an exponential extrapolation, a growth curve method and a trend extrapolation, etc.

In step 908, a corrected measured value of the environmental parameter may be determined based on the current measured value of the environmental parameter and the current measured deviation. As an example, the current measured value of the environmental parameter may be added to or subtracted from the current measured deviation to obtain the corrected (or “after the compensation”) measured value of the environmental parameter.

It should be noted that the above description of the compensation process of the measured value of the current environmental parameter is merely provided for convenience of description and not intended to limit the present disclosure to the scope of the embodiment. For persons having ordinary skills in the art, modules may be combined in various ways, or connected with other modules as sub-systems. Various variations and modifications may be made under the teachings of the present disclosure. However, those variations and modifications may not depart from the spirit and the scope of the present disclosure. For example, other selection or processing conditions may be added between the step 902 and the step 908. For example, the relationship among the obtained measured deviation of environment parameter of the device, the obtained electric power value of the device, and the obtained power-on duration of the device may be stored and backed up. Similarly, the storage backup step may be added between any two steps in the flowchart. For example, in some cases, if the conditions of the power-on duration, the current measured value of the environmental parameter, or the electric power value of the heat generating device 130 and/or the power-on duration of the heat generating device 130 correspond to the existing compensating temperature time relationship, the compensated value may be generated by directly querying the data in the compensating temperature time relationship.

FIG. 10 shows a schematic diagram of the reference temperature time relationship (the power of the heat generating device 130 remains unchanged) according to some embodiments of the present disclosure. The reference temperature time relationship may be expressed in the form of a table or function curve. As shown in FIG. 10, the temperature time relationship shows the relationship between the deviation for the measured value of the current ambient temperature of the first sensing device 201 relative to the measured value of the reference ambient temperature (referred to as “temperature deviation”) and the power-on duration of the heat generating device 130. Wherein T₀ may be the stable temperature deviation reached by the heat generating device 130 in the non-operating state. T₁ may be the stable temperature deviation reached by the heat generating device 130 in the running time for a long time. The stable temperature deviation may refer to the temperature deviation reached after the heat generating device 130 remains in the running state or the non-operating state for a long time. The longer time herein may be 1 hour, 2 hours, 5 hours or other time periods. The time to reach the stable temperature deviation may be related to a combination of one or more factors such as the type of heat generating device 130, the electric power of the heat generating device 130, the ambient temperature, and the ambient humidity. t_(r0), t_(r1), t_(r2), t_(r(x-1)), and t_(rx) may respectively refer to the power-on duration of the heat generating device 130 of one unit temperature rising at a time, for example, 0.1° C., when the temperature deviation rises from T₀ to T₁.

FIG. 11 is a schematic diagram showing the reference humidity time relationship (the power of the heat generating device 130 remains unchanged) according to some embodiments of the present disclosure. The reference humidity time relationship may be represented by the table or the function curve. As shown in FIG. 11, the humidity time relationship shows the relationship between the deviation for the measured value of the ambient humidity relative to the reference ambient humidity deviation (“humidity deviation”) and the power-on duration of the heat generating device 130. Wherein, H₀ may be the stable humidity deviation reached by the heat generating device 130 in the non-operating state. H₁ may be the stable humidity deviation reached by the heat generating device 130 in the running time for a long time. The time to reach the stable humidity deviation may be related to factors such as the type of heat generating device 130, the electric power of the heat generating device 130, the ambient temperature, and the ambient humidity, etc. τ_(r0), τ_(r1), τ_(r2), τ_(r(x-1)), rx may respectively refer to the power-on duration of the heat generating device 130 of one unit temperature rising at a time, for example, 0.1 g/m³, when the humidity deviation rises from T₀ to T₁.
